What kinds of Heat contracts exist?

Listings change through the season. Check the app for current listings. The common types:

• Game contracts. Will the Heat win tonight? ProphetX lists Moneyline, Spread and Total markets on NBA games.
• Season contracts. Regular-season wins over or under a number, playoff qualification, seeding.
• Futures. Eastern Conference champion. NBA champion. Priced all season.
• Player markets. Where listed, contracts on individual stats or awards. Our Florida player props guide covers these.

Every contract trades between 1 cent and 99 cents. Example: a contract priced at 62 cents implies about a 62% chance. That is an example, not a Heat price. For the mechanics, see how a contract works, step by step, and for the other teams, every Florida team's prediction markets.

How do you read a Heat price before you trade?

• Read the settlement rules. Two contracts that sound alike can settle differently. Does the Play-In count as "making the playoffs"? The rules page says.
• Check volume and the spread. A busy title market tells you more than a thin player market where one order moves the price.
• Know what moves it. Injuries. Trades. Rest days. A new star changes every Heat price on the board, and nobody has seen this roster play a game that counts.
• Compare exchanges. Each platform runs its own order book, so the same outcome can trade at slightly different prices. A small gap is usually liquidity, and fees can erase it.

Can you trade Heat contracts from Florida?

The Florida status line at the top of this page applies to every contract here: Kalshi, Polymarket US, OG and ProphetX carry the status Available (as of October 3, 2026).

One newer filing to know. On October 8, 2026 the Seminole Tribe sued DraftKings in Broward County circuit court, arguing that its sports prediction-market contracts are sports betting that only the Tribe may offer in Florida. The four exchanges above are not defendants in that case, and the status above was not re-checked after it was filed.

The national picture is unsettled. Three petitions asking the Supreme Court to review appeals-court rulings on sports event contracts (Nos. 26-299, 26-338 and 26-344) are pending, and none has been granted. So check the status again before you trade.

Kalshi's and Polymarket US's minimum age is 18. ProphetX's is 18, or the local age of majority if higher. OG's partner terms state no minimum age, so check its sign-up screen. We recommend 21+.

Where can you trade Heat contracts?

ProphetX leads our list for sports. New users: Trade $50, Earn $75! with code MIAPREDICTS, valid in 49 states + D.C. Make $50 of filled trades that open a position at $0.80 or below within 30 days of approval. The $75 comes as three $25 installments: the first within 24 hours of qualifying, the next two 7 and 14 days later, and only if you fully used the previous $25. Each expires after 45 days. Offer terms apply. Full verdict in our ProphetX review.

After that: Kalshi, then Polymarket US. Different order books, different prices, same game.

What do Heat trades cost in fees?

• ProphetX: 2% of net gains per market on straight trades.
• Kalshi: a transaction fee on the expected earnings of a contract, charged when a trade executes and shown on the order ticket.
• Polymarket US: Since October 2026 Polymarket US charges a taker fee on orders that fill straight away, worked out from the price: on standard markets it is highest for contracts near 50 cents (about $1.74 per 100 contracts) and falls toward 1 cent and 99 cents. Orders that rest on the book pay no fee; rebates on them are limited to very high-volume traders from October 19, 2026.

Trade only what you can afford to lose. If it stops being fun, stop, and see our responsible trading page.

Frequently asked questions

When is the Miami Heat's first game of the 2026-27 season?

The Heat open the 2026-27 season at home against the Minnesota Timberwolves on Wednesday, October 21, 2026, at 7:30 p.m. ET at Kaseya Center. The game is on ESPN.

What Miami Heat prediction markets can I trade?

The common types are single-game contracts, season contracts such as win totals and playoff qualification, futures on the Eastern Conference and NBA title, and player markets where listed. Listings change during the season, so check the app for what is open.

Can I trade Miami Heat contracts in Florida?

Kalshi, Polymarket US, OG and ProphetX carry the status Available (as of October 3, 2026) in Florida, and no Florida enforcement action against prediction markets was found. Florida's gaming regulator says online sports gaming outside the Seminole Tribe's sportsbooks is "most likely" illegal, without naming prediction markets, so check the status again before you trade.

Do Heat contracts settle the same way on every exchange?

Not always. The real-world result is the same, but each exchange writes its own rules, for example on whether the Play-In counts as making the playoffs. Read the rules page for the exact contract before you trade.

Why can the same Heat outcome have different prices on two exchanges?

Each exchange has its own traders and its own order book. Gaps between them usually come from liquidity or timing, and trading fees can erase a small gap.
